摘要翻譯:
對于在極小G/P中與Schubert變體的Bruhat偏序集相關(guān)的toric變體X,我們用相關(guān)的多面體錐面來描述奇異軌跡。我們進(jìn)一步證明了奇異軌跡在X中是余維數(shù)為3的純的。

英文摘要:
For the toric variety X associated to the Bruhat poset of Schubert varieties in a minuscule G/P, we describe the singular locus in terms of the faces of the associated polyhedral cone. We further show that the singular locus is pure of codimension 3 in X.
